我正在尝试为我的 Rails 项目设置 Capistrano 部署。服务器使用 rvm。我需要脚本来运行捆绑安装，因此需要 rvm 与 Capistrano 一起使用。
当我运行“上限生产部署”时，我得到了这个——有什么想法吗？

我在 deploy.rb 中有这个：
set :rvm_ruby_string, 'ruby-1.9.3-p194'
set :rvm_bin_path, '/usr/local/rvm/bin'
set :rvm_type, :system
和 Capfile：
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
和宝石文件：
gem 'capistrano'
gem 'capistrano-rails'
gem 'capistrano-rvm'
gem 'capistrano-bundler'
ls /usr/local/rvm/bin 显示：
